Summary: This study used MODIS MOD11A2 LST products to investigate the land surface temperature (LST) change in the Yangtze River Delta (YRD) region from 2001 to 2020. Various analysis methods were applied, including trend analysis, decomposition analysis, and landscape pattern analysis, to comprehensively assess the spatial and temporal variability of LST. The results revealed a range of linear change rates for LST in the YRD, with different warming trends identified. Breakpoints in LST were mainly found in the northern and southern YRD, occurring frequently during 2010-2013. Crop areas and high NDVI regions showed the most frequent breakpoints, with most of them within 2°C. Urban areas experienced stronger warming compared to other land types. This study provides important insights into the dynamics of LST in the YRD over the past 20 years and emphasizes the significance of accounting for breakpoints in regional temperature assessment.

Summary: Chlorine radical plays a crucial role in the formation of ozone and secondary aerosols in the troposphere. This study provides a comprehensive emission inventory for major atomic chlorine precursors in the Yangtze River Delta (YRD) region of China in 2017, with substantial emissions of HCl mainly from biomass burning and coal combustion, and fine particulate Cl- mainly emitted from industrial processing.

Summary: This study analyzed the total mercury concentration in suspended particulate matter in the Yangtze River and calculated the mercury budget in 2018 and 2021. The results showed significant variations in mercury concentrations along the river, with lower fluxes observed in recent years. The study suggests that emission control policies have had a positive impact on reducing mercury flux to the East China Sea, but more efforts are needed to further reduce mercury emissions.

Summary: The agricultural soils in China are heavily contaminated with polychlorinated biphenyls (PCBs). However, there are no effective management standards to control the health risks of PCBs exposure. This study analyzed the contamination characteristics and composition of PCBs in agricultural soils in south-eastern China over the past 20 years. The derived generic assessment criteria for PCBs are valuable for assessing and managing the contamination.

Summary: Understanding the distribution patterns and diversity maintenance mechanisms of phoD-harboring bacteria (PHB) is crucial for studying organic phosphorus mineralization. This study investigated the ecological processes shaping the landscape of PHB in soils and sediments along the Yangtze River, finding that PHB community similarity declined with increasing geographical distance and that sediments exhibited greater compositional variation. PHB in soils had higher alpha-diversities, broader environmental breadths, higher community stability, and stronger species replacement, while PHB in sediments showed stronger phylogenetic signals. Stochastic and differentiating processes were dominant in community assemblies of PHB in both soils and sediments. Electrical conductivity played a decisive role in shaping PHB diversity. These findings highlight the differences in distribution patterns of PHB between soils and sediments and provide insights into ecological processes in these ecosystems.

Summary: Droughts caused by global warming have a severe impact on the development of terrestrial vegetation ecosystems. This study analyzes the drought characteristics in the Yangtze River Basin using the Standardized Water Supply-Demand Index (SSDI) and finds that most regions show an increasing trend in drought. Accurate analysis of these characteristics is crucial for drought risk assessment and sustainable water resource development.

Summary: This study investigates the impact of urbanization on summer rainfall in the Yangtze River Delta using long-term observations and numerical simulations. The study finds that urbanization has led to increased summer rainfall in the region, particularly through the intensification of heavy rainfall events. The numerical simulations reproduce the observed urban rain island effect and show that urban expansion has increased summer rainfall over urban areas by an average of 51.91 mm. However, the urban rain island effect weakens in the later stages of urbanization, potentially due to the strengthening of precipitation-inhibiting effects.

Summary: This study develops a novel modeling approach based on grey prediction model and cloud model to predict and analyze energy consumption and energy security in the Yangtze River Delta (YRD) region. The ONMGM (1,1) model demonstrates the best prediction capability with reduced errors. The findings indicate a significant increase in energy consumption in Jiangsu Province, while Shanghai has lower total energy consumption. Moreover, the overall risk level of energy security is expected to rise sharply, and traditional energy security plays a vital role in the overall energy security of the YRD region.

Summary: The study found that air emissions in the lower Yangtze River area significantly impact the air quality and public health in the Yangtze River Delta. The emissions contribute to increased concentrations of PM2.5 and ozone, as well as higher exposure to nitrogen dioxide, leading to an increase in mortality rates. Therefore, reducing emissions in this area is beneficial to public health.

Summary: Supporting ecological protection and restoration is a core aspect of China's Yangtze River conservation strategy. This study provides an updated understanding of the spatial distribution and characteristics of heavy metals in soils of the Yangtze River Basin in China. The results show spatially-heterogeneous concentrations of various heavy metals, with higher pollution levels in the middle reaches of the river. The study also highlights potential health risks, particularly for children, due to elevated levels of heavy metals in certain areas.
